Book excerpt: “Terrifying” true stories of criminals who live seemingly normal lives, perfect for fans of Mindhunter—”these are the stories that keep me up at night” (Sgt. Joseph Kuns, LAPD). “He seemed so normal” is an all-too common sentiment from the neighbors of violent criminals when their heinous acts are finally exposed. There are often no obvious indicators that separate the pleasant neighbor from the sadistic murderer. Even serial killers like Jeffrey Dahmer, Ted Bundy, and John Wayne Gacy managed to circulate unnoticed among their communities. They are neighbors and students, professionals and friends living out criminal double lives. In Double Lives, true crime author Eric Brach presents both a nonfiction exposé and a nationwide search that details the exploits of some of the worst criminals in recent American history, all of whom succeeded in going undetected for years while perpetrating one crime after another—all in their own hometowns. Monsters of every race, age, gender, and socioeconomic class are profiled in this roller-coaster of crime. Along the way, the author discusses the criminals he grew up with in his own seemingly innocent community, and provides a personal look at the current scourge of opioid addiction, making Double Lives a sensational yet sobering read.
